Metallic service and meter poles shall be designed and constructed
so that the poles and parts thereof will not fail or be seriously distorted
at any load less than the maximum working loads (see Rule 43 for loadings)
multiplied by the safety factors specified in Table 4, Rule 44. The safety
factors specified in Table 4, Rule 44 shall be applied as follows:

Tension: The yield strength of the metal used shall be divided by the safety
factor specified in Table 4, Rule 44 to determine the maximum allowable
working stress.

Compression: The critical. buckling strength of the material used, as determined
by applicable formulas employing the effective slenderness ratio and yield
strength, shall be divided by the safety factors specified in Table 4, Rule
44, to determine the maximum allowable working stress.

Shear: The yield strength of the material used shall be divided by the safety
factors given in Table 4, Rule 44 to determine the maximum allowable working
stress.

Rule 48.6

48.6 Metallic Service and Meter Poles

Metallic service and meter poles shall be designed and constructed
so that the poles and parts thereof will not fail or be seriously distorted
at any load less than the maximum working loads (see Rule 43 for loadings)
multiplied by the safety factors specified in Table 4, Rule 44. The safety
factors specified in Table 4, Rule 44 shall be applied as follows:

Tension: The yield strength of the metal used shall be divided by the safety
factor specified in Table 4, Rule 44 to determine the maximum allowable
working stress.

Compression: The critical. buckling strength of the material used, as determined
by applicable formulas employing the effective slenderness ratio and yield
strength, shall be divided by the safety factors specified in Table 4, Rule 44, to determine the maximum allowable working stress.

Shear: The yield strength of the material used shall be divided by the safety
factors given in Table 4, Rule 44 to determine the maximum allowable working
stress.
